The best method for removing the gas content of pinto beans is to bring them to a boil and remove from the heat source. This process aids in releasing the sugars that can result in gas.
After beans have boiled a teaspoon of baking soda should be added to the water. The beans need to soak in the water overnight. Beans should be rinsed multiple times before use.
Canned beans do not have the gas content of dried beans. Therefore, canned beans do not need to go through the soaking process. Pinto beans are commonly served in broth, added to soups or mashed.
